DETAILED DESCRIPTION OF THE PRESENT INVENTION

The technical content, structural features, objectives, and effects ofthe present invention are described in detail with reference to theembodiments and attached drawings.

See FIG. 1. The present invention provides a water-saving toilet bowl,comprising a toilet bowl body 1 and a water tank 2 disposed on toiletbowl body 1. The toilet bowl body 1 is provided with a flushing waterchamber 11. The flushing water chamber 11 is connected with water tank2. Water tank 2 is provided with a switch 21. A flushing water value isdisposed between the water tank 2 and the flushing water chamber 11. Theswitch 21 controls the opening and closing of the flushing water valveto realize flushing of the toilet bowl.

The drain pipe 111 of the flushing water chamber 11 is connected with anoutside sewage pipe through a water-saving device. The water-savingdevice comprises a case, a hose 4, and a valve component which controlsthe closing and opening of hose 4.

The valve component comprises a rotor 51, a rotating shaft 52, and afirst pressing member 53. Hose 4 is disposed in the case in an inclinedway; one end of hose 4 is connected with the drain pipe 111, while theother end is connected with the outside sewage pipe. The rotating shaft52 is disposed on the case. The rotor 51 is rotationally disposed on therotating shaft 52. The first pressing member 53 is disposed at the frontend of the rotor 51. The first pressing member 53 presses hose 4 toimplement closing and opening of hose 4 when the rotor 51 rotates.

Hose 4 is disposed in an inclined way and is connected with the drainpipe 111 and the outside sewage pipe. When sewage in the flushing waterchamber 11 is flushed away, the sewage and the water are directlydischarged into the outside sewage pipe through the inclined hose 4.Different from the traditional toilet bowl, the drainage is downwardinstead of upward, and the sewage can be easily flushed away usinglittle water.

Wherein, the outside sewage pipe can be disposed in many ways. In oneembodiment of the present invention, the outside sewage pipe is a lowersewage pipe 31 or a rear sewage pipe 32. The specific type of the sewagepipe is disposed upon the specific installation position of the toiletbowl.

Specifically, hose 4 is not limited in material by the presentinvention, and preferably, is a silicone hose. Of course, the presentinvention does not limit the specific material of hose 4.

Wherein, this application provides preferable embodiments for theinstallation and fixation of hose 4. The end of hose 4 is connected andfixed with drain pipe 111 and the outside sewage pipe is fixed by a ringhoop. Specifically, the two ends of hose 4 are respectively providedwith fixing slots that extend in the circumference; the water-savingdevice is also provided with a ring hoop; and the ring hoop is disposedin the fixing slots to fix hose 4 on drain pipe 111 and the sewage pipe.The fixing slots further limit the axial movement of the ring hoop. Thefixation is firm; the dismantling is convenient; and the use is simple.

The toilet bowl body 1 is provided with a case inside, or the waterclose body 1 itself is the case. The case conducts the function offixing rotating shaft 52. Rotor 51 is rotationally disposed on rotatingshaft 52. In this embodiment, rotor 51 is composed of rotating plateswhich are disposed parallel to each other; the middle parts of therotating plates have rotating holes through which rotating shaft 52penetrates through. In this embodiment, the first pressing member 53 isa pressing rod; the two ends of the pressing rods are respectivelyconnected with the two rotating plates; and hose 4 extends through thespace between the pressing rod and the rotating shaft 52. When therotator 51 rotates towards hose 4 along the pressing rod 4, the pressingrod presses hose 4 to reduce the cross section of hose 4 andcontinuously rotates to close hose 4 and in such circumstances, therotator 51 rotates in the reverse direction to open hose 4. The rotor 51is shaped like a rocker on the rotating shaft 52, alternativelycontrolling the opening and closing of hose 4.

The rotor 51 in the rocker mode in one embodiment is specially asfollows: the rotor 51 is connected with a drive rope 6 which pulls therotor 51 to rotate; and the drive rope 6 is linked with a switch 21. Inthe normally unused situation, hose 4 is closed, and in suchcircumstances, the first pressing member 53 presses hose 4. After use ofthe toilet bowl, press the flushing switch 21 on the water tank 2, thenthe drive rope 6 drives the rotor 51 to rotate, the flushing water valveopens, the water tank 2 flushes the flushing water chamber 11, and thenhose 4 opens to drain the sewage.

The rotor 51 in the rocker mode in another embodiment is as follows: thedrive rope 6 is connected to the rear end of the rotor 51; thewater-saving device is also provided with a reset spring 7; one end ofthe reset spring 7 is connected to the rear end of the rotor 51, whilethe other end is fixed on the case.

When the toilet bowl is not used, the first pressing member 53 closeshose 4 and the spring is at the normal position. When the toilet bowl isflushed in use, press the switch 21 for flushing while the drive rope 6pulls the rotor 51 to rotate to open the hose 4 so as to drain thesewage. When the toilet bowl is not used, the force acting on the driverope 6 disappears, and the rotor 51 resets to the original position bythe effect of the reset spring 7.

The outer side of the water tank 2 can be provided with a housingthrough which the drive rope 6 can penetrate, ensuring that the entiretoilet bowl has a beautiful appearance.

Furthermore, to valid the situation that hose 4 is entire bent and failsto close when pressed by the first pressing member 53, in thisembodiment, the case is provided with a first fixing block 81. The firstfixing block 81 is disposed on the other side of hose 4 relative to thefirst pressing member 53 and pressed against hose 4. When the firstpressing member 53 presses hose 4, the movement of hose 4 is limited bythe effect of support of the first fixing block 81, thus realizing theclosing and opening of hose 4.

When the toilet bowl is not used, hose 4 is closed, which means thatwater is not discharged into the sewage pipe. If the toilet bowl leakswater, water will flow into the flushing water chamber 11 without stopand finally overflow out of the toilet bowl. To avoid such situation, inthis embodiment, the water-saving device also comprises a siphon 9. Thesiphon 9 is disposed on hose 4 in a reverse “U” shape. The peak of thereverse “U”-shaped siphon 9 disposed is lower than the toilet bowl body1 but higher than the water level in the flushing water chamber 11. Thesiphon 9 may have a smaller inner diameter;

The siphon has two functions. One is to generate an absorption forcewhich generates siphonage through the siphon to continuously bring awaywater (or air) in the toilet bowl when the sewage hose is sealed and thesewage in the lower sewage pipe is pulled downward continuously, thusensuring smooth sewage discharge.

The other is to prevent water leakage. In the case that hose 4 isclosed, when the toilet bowl leaks water and the water level is higherthan the peak of siphon 9, water flows out from siphon 9 by the effectof the pressure difference. Meanwhile, some sensors can be installed toprompt the users.

Moreover, siphon 9 is closed when hose 4 is used, avoiding the situationthat the sewage is shunted by siphon 9, causes smaller flushing force ofhose 4 and results in water waste. Meanwhile, the sewage is alsoprevented from being clamped in siphon 9 to cause failure ofanti-leakage. Therefore, in this embodiment, the rotor 51 also extendsto form a rotating end 54. The top of rotating end 54 is provided with asecond pressing member 55. The second pressing member 55 presses siphon9 to implement closing and opening of siphon 9 when rotor 51 rotates. Insuch circumstances, the connecting plates are trifurcate plates, and theprinciple is similar to that of the first pressing member 53 andtherefore is not repeatedly described. It should be noted that hose 4and siphon 9 are alternatively to be opened and closed, which means thatwhen hose 4 is open, siphon 9 is closed, while when hose 4 is closed,siphon 9 is open. Therefore, when the first pressing member 53 is resetand hose 4 is pressed by the effect of reset spring 7, the secondpressing member 55 turns to the direction away from siphon hose 4.

In this embodiment, the case is provided with a second fixing block 82.The second fixing block 82 is disposed on the other side of siphon 9relative to the second pressing member 55. In another embodiment, thefirst fixing block 81 and the second fixing block 82 are a whole body.

In this embodiment, one end of hose 4 close to the sewage pipe isprovided with a valve 41 which allows the fluid to flow in onedirection. Valve 41 functions as a one-way valve. When discharged, thewater flushes open the opening in the middle part of valve 41. When thetoilet bowl is not used, the opening is closed to prevent the terriblesmell in the sewage pipe from flowing back into the room.

The above mentioned description is only the exemplary embodiment of thepresent invention, which cannot limit the present invention. Within thespirit and principle of the present invention, any modification of theequivalent structure, or direct or indirect application in other relatedtechnical fields all shall be included in the protection scope of thepresent invention.
